Describe the issue

When I am trying to proxy the RTSP Stream running on my fritzbox 6660 Cable I am getting this error as soon as I am starting the rtsp-simple-server file:

2022/08/25 14:44:17 INF [path proxied] [rtsp source] ERR: sdp: invalid syntax c=In IP4 0.0.0.0 (c=In IP4 0.0.0.0)

My conf file looks like this:

paths:
proxied:
source: rtsp://192.168.177.1:554?/avm=1&freq=602&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=1&pids=0,16,17,18,20,1003,130,131

Using VLC to stream the same url works with no Problem.
Using a different IP than my fritzbox's, like my printer's ip leads to a different error message.
Also I tried your deprecated rtsp-simple-proxy and it works but the connection is crashing every 10 seconds.

Describe how to replicate the issue

1. add the ip of the fritzbox into the source block of any path. Adding query parameters does not change the result.
2. start the rtsp-simple-server
3. watch the error message get posted every 5s or so.
